Universitat Autònoma de Barcelona researchers have developed a system that efficiently transfers electrical energy between two separate circuits. The system, made with a shell of metamaterials that concentrates the magnetic ...

Tesla announced what it calls its "most affordable" electric vehicle in the Model 3 last week. The car can now be ordered with a deposit of A$1,500 in Australia (US$1,000 in the United States) but won't be delivered until ...

Electric cars will only be truly competitive when it doesn't take longer to charge them than it does to fill a gas tank. The storage capacity of batteries is improving exponentially, but the power grid is the weak link: how ...

The details of how charge carriers form within a solar cell and then generate an electric current have remained unclear. A breakthrough by a trio of researchers at the University of Tsukuba (Ibaraki, Japan), as reported in ...

Whether it is in catalytic processes in the chemical industry, environmental catalysis, new types of solar cells or new electronic components, nanoparticles are everywhere in modern production and environmental technologies, ...

Our world is ruled by four fundamental forces: the gravitational pull of massive objects, the electromagnetic interaction between electric charges, the strong nuclear interaction holding atomic nuclei together and the weak ...
